Thank you so much for respond to my issues.
I think you are right. I am missing something on the
Cisco 7204 but I don't now what it is.
I have captured debug log files from both radius and Cisco.
Please let me know if you want me to post them.
*****Here is what I have for our cisco 7204.********
aaa new-model
aaa authentication login default local
aaa authentication login console enable
aaa authentication login telnet line
aaa authentication ppp default group radius local
aaa authorization network default group radius local
aaa accounting delay-start
aaa accounting nested
aaa accounting exec default start-stop group radius
aaa accounting network default start-stop group radius
enable secret 5 $1$xxxxxxxxxxxxxxxxxxxxxx/
vpdn enable
vpdn aaa override-server 172.17.17.17
!
radius-server host 172.17.17.17 auth-port 1645 acct-port 1646
**** Here is one of our users profile (users file) ****
campbell Auth-Type := Local, User-Password
== "1etelrx23"
Service-Type = Framed-User,
Framed-Protocol = PPP,
Framed-IP-Address = x.x.172.7,
Framed-IP-Netmask = 255.255.255.128,
Framed-MTU = 1492
#
DEFAULT Service-Type == Framed-User
Framed-IP-Address = 255.255.255.254,
Framed-MTU = 1492,
Service-Type = Framed-User,
Framed-Protocol = PPP,
MS-Primary-DNS-Server = x.x.230.195,
MS-Secondary-DNS-Server = x.x.230.196,
Session-Timeout = 86400
What am I missing?
Thanks,
Tom
